场景: 当我们想要通过接口查询某个组织下的用户列表时,需要先进行组织切换,然后查询对应组织下的用户列表,涉及的接口包括下面两个: 切换组织接口:/de2api/user/switch/{oId} 查询用户列表接口:/de2api/user/pager/{goPage}/{pageSize} 接口调用

场景:

当我们想要通过接口查询某个组织下的用户列表时,需要先进行组织切换,然后查询对应组织下的用户列表,涉及的接口包括下面两个:

切换组织接口:/de2api/user/switch/{oId}

查询用户列表接口:/de2api/user/pager/{goPage}/{pageSize}

接口调用步骤如下:

1、进入 API Key 页面,创建 API Key,创建后获取到 accessKey 和 secretKey(API Key 是访问 DataEase API 的密钥,具有账户的完全权限)。

2、根据获取到的 accessKey 和 secretKey,生成接口调用需要的 token 认证信息,写入请求头的 x-de-ask-token 参数中进行接口调用,切换组织后,需重新生成 token 认证信息,然后调用获取用户接口获取组织下的用户列表,参考以下代码示例。

            while ((line = reader.readLine()) != null) {
                responseBody.append(line);
            }
            System.out.println("响应体:\n" + responseBody);
        } catch (Exception e) {
            e.printStackTrace();

    public static String aesEncrypt(String src, String secretKey, String iv) throws Exception {

        byte[] encrypted = cipher.doFinal(src.getBytes("UTF-8"));
        return Base64.encodeBase64String(encrypted);
    }
}

运行上面的示例代码,需要在 pom.xml 中引入以下依赖

<dependency>
    <groupId>com.auth0</groupId>
    <artifactId>java-jwt</artifactId>
    <version>3.12.1</version>
</dependency>

<dependency>
    <groupId>commons-codec</groupId>
    <artifactId>commons-codec</artifactId>
    <version>1.15</version>
</dependency>
